Hades

As the formidable ruler of the Underworld, this mythological deity serves as the ultimate antagonist during the final saga of Saint Seiya. Driven by a deep-seated disdain for humanity’s perceived ingratitude toward the heavens, he seeks to annihilate mankind and transform Earth into a lifeless wasteland. An ancient and bitter rival to Athena, his relentless quest for destruction poses the greatest threat to the survival of the human race and the gods alike.
